Trucks were powered by low-emission engines from International, Cummins and Caterpillar.
International Truck and Engine Corp. showcased its latest equipment and service upgrades in conjunction with emissions-compliant technology at a ride-and-drive event in February.
The event, held at the Phoenix International Raceway, spotlighted 40 heavy-duty and severe-service vehicles in typical work environments on paved courses and off-road tracks. All trucks were equipped with International, Cummins or Caterpillar engines to acquaint customers with the new technologies being used to meet federal environmental regulations. Both Cummins and International have developed exhaust gas recirculation (EGR) technology to meet the new standards while Cat has opted to develop engines using advanced combustion emission reduction technology (ACERT).
Company executives emphasized how International has engineered upgrades into its trucks beyond what was necessary to accommodate new compliance technologies. They include:
“We have added new air and chassis suspension and stiffened the floor to improve ride, especially under the seat,” said Tom Osborne, International engineer. The new wide track with 35-inch spring centers improves wheel cut by 10 percent in the 9000 Series heavy application models, for example. Taper leaf front suspension reduces side sway and improves handling in general.
